Plantar fasciitis is a painful inflammation of the plantar fascia, a fibrous band of tissue on the bottom of the foot that helps to support the arch. Plantar fasciitis occurs when this band of tissue is overloaded or overstretched. This causes small tears in the fibers of the fascia, especially where the fascia meets the heel bone. Plantar fasciitis is common in obese people and in pregnant women, perhaps because their extra body weight overloads the delicate plantar fascia. It is also more common in people with diabetes, although the exact reason for this is unknown. Plantar fasciitis also can be triggered by physical activities that overstretch the fascia, including sports (volleyball, running, tennis), other exercises (step aerobics, stair climbing) or household exertion (pushing furniture or a large appliance). In athletes, plantar fasciitis may follow intense training, especially in runners who push themselves too quickly to run longer distances. Worn or poorly constructed shoes can contribute to the problem if they do not provide enough arch support, heel cushion or sole flexibility.
Plantar fasciitis is one of those injuries that magically seems to appear for no apparent reason. However, plantar fasciitis is caused by one of two methods. They are either traction or compression injuries. Plantar fasciitis is most often associated with impact and running sports, especially those that involve toe running rather than heel running styles. It is also commonly diagnosed in individuals with poor foot biomechanics that stress the plantar fascia. Flat feet or weak foot arch control muscles are two common causes of plantar fasciitis.
Plantar fasciitis is the inflammation of the plantar fascia – a band of tough fibrous tissue running along the sole of the foot. It occurs when small tears develop in the plantar fascia, leading to inflammation and heel pain. The plantar fascia tissue branches out from the heel like a fan, connecting the heel bone to the base of the toes. When the foot moves, the plantar fascia stretches and contracts. The plantar fascia helps to maintain the arch of the foot in much the same way that the string of a bow maintains the bow’s arch. The most notable symptom of plantar fasciitis is heel pain. This is typically most severe in the middle of the heel though it may radiate along the sole of the foot. The pain is most often felt when walking first thing in the morning or after a period of rest. As walking continues the pain may decrease; however some degree of pain remains present on movement. The pain may disappear when resting, as the plantar fascia is relaxed. Redness, swelling and warmth over the affected area may also be noticed. The onset of plantar fasciitis is gradual and only mild pain may be experienced initially. However, as the condition progresses the pain experienced tends to become more severe. Chronic plantar fasciitis may cause a person to change their walking or running action, leading to symptoms of discomfort in the knee, hip and back.
X-rays are a commonly used diagnostic imaging technique to rule out the possibility of a bone spur as a cause of your heel pain. A bone spur, if it is present in this location, is probably not the cause of your pain, but it is evidence that your plantar fascia has been exerting excessive force on your heel bone. X-ray images can also help determine if you have arthritis or whether other, more rare problems, stress fractures, bone tumors-are contributing to your heel pain.
Non Surgical Treatment
Treatment of heel pain caused by plantar fasciitis begins with simple steps. There are a number of options for treatment of plantar fasciitis, and almost always some focused effort with nonsurgical treatments can provide excellent relief. In rare circumstances, simple steps are not adequate at providing relief, and more invasive treatments may be recommended. Typically, patients progress from simple steps, and gradually more invasive treatments, and only rarely is surgery required.
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.
Do not walk barefoot on hard ground, particularly while on holiday. Many cases of heel pain occur when a person protects their feet for 50 weeks of the year and then suddenly walks barefoot while on holiday. Their feet are not accustomed to the extra pressure, which causes heel pain. If you do a physical activity, such as running or another form of exercise that places additional strain on your feet, you should replace your sports shoes regularly. Most experts recommend that sports shoes should be replaced after you have done about 500 miles in them.
